CC   -!- FUNCTION: Activator of specific mitochondrial mRNAs. PET54 is involved
CC       in the excision of intron aI5-beta from pre-mRNA for cytochrome c
CC       oxidase I (COX1) and plays a role in promoting the translation of COX3
CC       (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane {ECO:0000250};
CC       Peripheral membrane protein {ECO:0000250}.
